Today, after learning this and that about animal photography, I would try to capture the scene in a slightly better way. First I would try to not cut off the ear. And then I would try to get further down to get more at eye level of the bunny. A lower aperture value would also be nice to better seperate the animal from the background. But the aperture value was already the lowest possible with the lens I had used at this time.
The lens of my choice was my EF-S 55-250mm f/4-5.6 Kit zoom lens. The photo was taken with maximum zoom at 250mm. Camera was in P mode and ISO in AUTO mode. The camera had calculated for the scene an ISO value of 250, aperture value of f/5.6 and a shutter speed of 1/250 sec.
